Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To rationalize the amount of money for inheritance by roughly estimating the amount of money needed for primary inheritance and secondary inheritance from an owner or his or her mate on the basis of the tentative net total amount of left property in every specific period. SOLUTION: The total amount of left property is roughly calculated from the current prices of the lot, existent buildings, etc., and on the basis of the total amount of left property, a current inheritance tax evaluated amount is calculated (ST10). The business income and expenditure of a planned building functioning most effectively to future primary inheritance or secondary inheritance from the owner or mate are calculated (ST11). Here, when the most rational amount for inheritance is judged, it is judged again whether a building for business as a rental building plan is profitable (ST13). Correcting simulation is performed (ST14). When it is known that the plan is profitable after the correcting simulation, it is judged again whether the amount for inheritance is rational, for example, tax saving effect is large (ST17).
